After revealing some damning evidence that exhibited Paul Heyman's connection to both Brad Maddox and The Shield, the WWE Chairman had made up his mind to fire Heyman in front of the entire WWE Universe. But just as Mr. McMahon was about to send Heyman packing with two notorious words, Brock's music reverberated throughout the arena and the hulking behemoth laid out Mr. McMahon with a crushing F-5, which appears to have inflicted serious injury on the WWE Chairman.

It remains to be seen why Brock has returned to WWE after a five-month absence to target Mr. McMahon or what role, if any, Heyman had in such a vicious assault.

As seen at the end of Raw earlier tonight, Brock Lesnar made his return to the WWE by interrupting the firing of Paul Heyman and giving the F5 to Vince McMahon. This is the first time we have seen him since the Raw after Summerslam when he walked out on the company and also the first time since he extended his deal with WWE for another 2 years a few days ago.
